Solution

  • The error is caused either by Grails or by your application, you will need to determine why; it certainly seems to be happening relatively late in the pipeline since you are getting the correct HTML back (I assume you aren't explicitly rendering a 500 status code in your code by accident).

    As for the response you are getting back, it is ignored due to the 500 status. The $.get function accepts a callback which is only invoked on successful requests. If you put debug lines into your fnback function you will see it is never called. If you were to replace the $.get with an equivalent $.ajax call and provide an error callback, that function would get the HTML you are seeing returned in the browser's dev tools.
